To all whom it may concern:

Be it known that we, Lucius H. CAMMAGK and HENRY A. BROWN, citizens of the United States residing at Huntiiigi ton a in the county of Cabell and State of West Virginia, have invented a new and useful Ro tary Advertising Device. of which thei ol- This invention relates to changeable e xhibitors, the primary object ofthe invention being to provide means for moving; advertising or display cards to-a position adjacent. the display opening of the device, at

redetermined intervals. v

Another object'oit the-invention is to pro vide a plurality of independent card supporting frames. means being providedtch continuously rotating the frames to bring; them to positions'at the upper'portion of the casing, whereby they may fall bygravity to their active positions.

Another ob ect of the invention is to provide a novel form of switch actuating means employed for intermittently controlling the operation of the solenoid forming a part of the operating" means to accomplish the rotation of the card supporting frames.

With the foregoing and other ob ects in view which will appear as the description proceeds, the invention residesin the come ,binatio'n and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may bemade witlriinthe scope of what'is claimed without departing from the spir t of the invention; I

same a portion of the frame supporting the cards, forming the essence of the invention, may be. viewed.

Supported bv the end walls of the lions-- inn, is a main or supporting shaft indicated at 6, which has hubs 7 secured thereto at points adjacent to the ends thereof, the hubs including opposedinembers 8 and 9 respectively. with grooves 10 to accommodate the right angled ends llo'f' the legs 12. that form a part of each of the card supporting frames. A bar 13 forms a part oi each oft-he card supporting frame. and is secured along the outer edge thereof. each bar supporting a keeper indicated at 14-. the'keep ers being designed to cooperate. with the movable. finger l5 employed for moving the! frames to positions adjacent the display opening. r

ported within thchoiisinn. and has connection with the operating arm-t7 at one. end thereof. the arm 17 being p votally.supported as at 18 to permit the same to roclein a vertical plane.

One end of the arm 17 terminates ,at a.

pointadjacent to the rear wall ofthe lionsing. and has connection-with the arm 19 as at 20; whereby movement of the 'arm 19 Supported by the right angled portion 21'" of the arm 19 is a bar 25 formed with an opening to accommodate the lower extremity of the rod 26 and permit the rod 26 to move with respectto'the bar25, when.

the mechanism is in operation; .A coiled spring indicated at 27 connects-the 1"od26 and bar 25-, suitable adjusting means =-inclicated at 28 being); provided to adjust the-tensi on of the spring27.

As shown,- the upper extremity of the rod" 26 has connection with the. movable'fi-nger 29 which is pivotally supported as at :30,

The members 8' are formed,

The movable finder l5 pivotally sup I the forward extremity of the finger 29 being 7 curved as at 31 to contact with the keeperv of the card supporting frame that has been moved to the forward portion of the housmg. I V i l v 1 Associatedwith the arm l'? is a movable switch member 32 that hasinclinedwalls 33 and 34 forn'iedat the ends thereof, which walls cooperate with the depending fingers 35 and 35 that are'carried by the arm 17 to cause the movable member '32 toreciprocate when the arm 17 is moved.

Carried by the movable si'vitch m'eiinber 3 2 is a movable contact member 36 adapted to move into engagement with the sta tionary contact member 371:0 complete the circuit to the solenoid 24- to: cause the same to draw its core upwardly;

The lower end of the rod 22"carrie s a piston 38 thatmovesan the cylinder 39110 retard movement of the rod 22v when the same is moving downwardlyby gravity. In order that the air within thelcylinder 39 may exhaust, a tube l0 is providechf through which tube the air passes from the cylinder 39' upon the downward.movement of the piston 38.

A' pivoted' finger 411 also engages the keepers 14: and prevents reverse movement ofthe ser es of card supporting frames;

when the same have been moved in anticlockwise dlrectlons to expose another card.

' Coiled springsl2 connect the fingers 4L1 and 15, witha portion of the device to cause of their: inward movements where the" up er extremities thereof will lie within the path of travel of the keepers as the t-mines are being rotated withlnthehousing.

The" cards which'embody the have 3 drawings. TWhen two frames are moved to v movem'ent'ofthis rod 22 moves the: arm 17 causing the finger to-move over: thesurface '34 resulting in a sliding movement of- I the switchme'mber '[As the switch'mem positions as shown by Figure 2 of the draw mgs'the cards which are lllCllCEtllCCl at take pos tions as shown in Figure 2to' dis play the sign before the display opening of the device;

Inthe operationof thedeviceyFigure .o'f-the drawings discloses the same after" the solenoid has acted to drawits coreupwardly, the contact member's'36 and 37 being out of contact with each other pBF1T]li3- ting'the rod 22 to. move downwardly by gravity. It follows" that the downward ber132 moves to bring the contact members 36 and 37 1nt'o contact, the solenoid. is again energized, whereby the finger 15' vmoves downwardly causing the severalcardsupporting frames to rotate 1n an antl-olockwise direction.

ger's to be normally held to the limit gravity to a position adjacent to the finger 15 to display the sign.

It will. thus be seen that varioussigns may be placed on the cards between adjacent frames,' to the end that'theywi'll be displayed before the display opening of the housing, as the machine is put into opera tion.

Having thus describedthe inventioin what is claimed as new 1st 1. In a device of the character described; e

a housing, a shaft supported in the hous-' ing, a plurality of card supporting frames movable on theshaft, each of saidframes including a pair of legs, aba r supported" by the legs and carrying" a keeper, pivoted fingers having connection with the keepers to, release the frames at predetermined intervals; electrically controlled means for op eratingthe fingers, and cards carried by the frames." I p e v v v 2. In ELClGVlCB-IO'E thecharacter described,

3. In a device of the characterdescribed, a housing, a plurality' of hinged card-supporting frames supportedwithin the housing, a keeper carried-by ,"each "frame, a

pivoted finger operating in the upper iportion of the: housingyand' adaptedto contact with one of 'the keepers for preventing movement of the 'frames apivoted finger operating at the base of the housingand contacting with the. keepers for restricting movement of the frames in the opposite di-' rection, and means for operating the fingers to control the movements of the frames,

Intestimony Itha-t'we claim the foregoing as'our own, we have hereto afiixejd our signa turesin the presence of two witnesses,
